2.1. Clean the Hopper
Thank you for purchasing our banknote counters IMC08.
After starting the machine, it will go on self-check automatically. If the preset window shows the error code or tell
you to clean the sensors, generally speaking, it is because of dust on the surface or sensor blocked by notes. So
please clear the dust on the surface with brush or soft cloth, or take the notes away. Then restart the machine.
This document describes the error handling guideline and the maintenance manual.
2.0. Cleaning the Machine
Any dust, dirt or other substances sticking to the sensor will interfere with the normal operation of the sensor
and cause erroneous counting results. Therefore, the sensor and roller shaft shall be cleaned with the
attached cleaning tools as necessary every day.
Please turn off the power switch before cleaning to prevent electric shock or other injury accidents.
Please do not use chemicals such as benzene, thinner or water.
There are 3 parts need to be clean in the hopper: hopper sensor, banknote processing wheel and the banknote
entrance, please use the nylon brush to clean them.

3.5. Sensor Errors
If the wheels in the hopper are consistently spinning after the machine powers on, and then stops with the
“hopper sensor error”, the hopper sensor is too sensitive.
3.5.1. Hopper Sensor Error
If the impeller is always spinning, or the “stacker sensor error” indicated on the screen, that means the stacker sensor
doesn’t work or too sensitive.
3.5.2. Stacker Sensor Error
If the number of banknote counting is always not correct, that means the counting sensor error doesn’t work. Please
clean the machine first.
If the error still happens, please contact us for machine repairment.
3.5.3. Counting Sensor Error
Too loose the feeding gap causes two bills to pass through at the same time, and the two bills that pass through
at the same time will enter the reject port, but the number of bills at the reject port only shows an increase of 1,
resulting in a counting error.
At this time, you can solve the counting problem by turning the screw counterclockwise, adjusting the feeding gap
according to section 3.5, and tightening the feeding gap until just one bill can pass through.
Please use the marker pen to paint a little on the hopper sensor as shown in the above figure.
The IMC08 banknote counter will take a few seconds to conduct a self-check with spinning the counting wheels
after power on. The IMC08 will check the sensors, the following errors may happen if the sensors have been blocked
or damaged.
3.6. Feeding Gap Calibration
Figure 3-6 Use Marker Pen to Decrease the Sensitivity of Hopper Sensor
Screw

1) Turn off the auto counting feature.
2) Insert one banknote into the gap between the rollers to check if the banknote can be inserted smoothly,
as shown in the following.

Figure 3-10 The Banknote Feeding Gap
Figure 3-11 One banknote to Check the Gap between the Rollers
If the banknote is hard to insert, that means the feeding gap is too small. Rotate the screw clockwise until the banknote
can be inserted smoothly. If the feeding gap is so large that two or more banknotes can be inserted to the feeding gap,
please rotate the screw counterclockwise until the gap can just allow one banknote at a time.
The screw above is used to control the width of the feeding gap. You can use a coin to adjust the gap easily.
The width will become bigger by rotating the screw clockwise toward the biggest dot. Turn counterclockwise to
decrease the gap.
To fine tune the feeding gap, do the following:

3.7. CIS Calibration3) Use the banknote to check the other sides of the gap between rollers, to make sure the banknote can be inserted
into both sides of the feeding gap smoothly. CIS calibration is often needed when there are many errors during the banknote counting process.
1) Please enter the main menu. Next, go to the service menu with the password “9999”, as shown in the following
figures.
The IMC08 needs different gaps for different currencies, but otherwise should stay consistent. Having the correct
feeding gap adjusted will ensure smooth operation as well as a trouble-free experience. You may need to do some
trial and error before getting it perfectly smooth.
You may also wish to make his adjustment over time, When the banknotes are not fed smoothly through the machine
or several error messages are occurring often such as: Bill Double Error, Chain Notes Error or Half Notes Error.
Other reasons that might require to readjust the feeding gap are:
- The counting of new or mint condition bills.
- The counting of poor or badly deteriorated bills.
- Polymer notes and paper-made notes counted together.
